Electric Circuit

Electric Circuit

A lot of appliances and devices in our houses uses electricity. Hence, electricity is an important element in our life.

7.1

Electric Circuit

Electricity is an important thing in human's daily life.

Electric Component and Its Functions

An electrical circuit is a complete circuit that allows electric current to flow through it.

An electric circuit is made up of multiples components such as:-

Electric circuit

Connecting the bulb, dry cell and switch with wires will create one electric circuit.

The switch is a component in the circuit that can connect and break the electric current in the circuit

When the switch is closed, the electric current will flow and causes the bulb to light up.

When the switch is opened, the electric current will not flow and causes the bulb not to light up.

Why does not the bulb light up?

There are multiples reasons why a bulb does not light up.

For examples:-

1.	The bulb is broken

2.	The dry cell does not have enough energy

3.	Wrong-way of installing the bulb

4.	The wire is not connected correctly

5.	The switch is off

Conductor and Insulator

A conductor is a material that allows electric current to flow through it.

An insulator is a material that does not allow the electric current to flow through it.

Examples of conductor and insulators:-
